•use the UP and DOWN buttons to scroll the parameters. The LED corresponding to the category of parameters will be on;
•press SET to display the value associated with the parameter increase or decrease the value using the UP or DOWN button respectively;
•press SET to temporarily save the new value and display the parameter again;
•repeat the procedure for any other parameters that need to be modified;
•press the SET button for more than 3 s to permanently save the parameters and exit the parameter setting procedure.
